Abstract: The present invention discloses a micro-optical phase film and a micro-lenticular lens. The optical phase film is integrally formed and includes an optical phase film base and a concave surface disposed on the optical phase film base. The concave surface has a plurality of concave and semi-cylinder like protrusions which are separated from each other in a constant pitch and have the same height. A lens layer covers the optical phase film to form a micro-lenticular lens. The optical phase film will exhibit different refractive index because of the incident light with different polarization angles, so as to achieve the object of 2D/3D image switching.

Abstract: The present invention provides a micro-retarder film for a 2D/3D image switchable display. The micro-retarder film comprises a first homogenous layer, a microstructure phase layer with a plurality of retarder patterns formed on the first homogenous layer alternately, and a second homogenous layer formed on the microstructure phase layer.

Abstract: The present invention discloses a microstructure optical phase shifting film and lens. The optical phase shifting film is an integrated structure which includes a light-phase-shifting-film base and the convex surface positioned thereon. The convex surface has a plurality of semi-cylinder like protrusions which have the same height and are separated from a constant pitch with each other. A lens layer is covered on the surface of the optical phase shifting film to form a microstructure lens. The optical phase shift film exhibits different refractive index because of the light with different polarization angle. Therefore, the microstructure functions as a lenticular lens used in 2D/3D switching display.
